IO Utilities (IMPaCT_IO)

Utility functions for saving and loading Armadillo matrices and vectors to/from HDF5 format. Defined in src/IO_utils.h.

template<typename T>
void saveData(const T &data, const string &default_filename, const string &data_name)

Save an Armadillo matrix or vector to an HDF5 file.

Parameters:

  • data – The matrix or vector to save.

  • default_filename – Output filename (e.g., "ss.h5").

  • data_name – Human-readable name for error messages.

If data is empty, prints a warning and does not create a file.

template<typename T>
void loadData(T &data, const string &filename, const string &data_name)

Load an Armadillo matrix or vector from an HDF5 file.

Parameters:

  • data – The matrix or vector to load into.

  • filename – Path to the HDF5 file.

  • data_name – Human-readable name for error messages.

std::vector<int> getSortedIndices(const vec &values, bool ascending = true)

Return indices that would sort the input values. Used internally by GPU sorted synthesis functions.

Parameters:

  • values – Armadillo vector of values to sort.

  • ascending – Sort order (default: ascending).

Returns:

Vector of indices in sorted order.
